Question

As a way of determining the inductance of a coil used in a
researchproject, a student first connects the coil to a 13.0 V
battery and measures a current of0.660 A. The student then connects
thecoil to a 24.0 V (rms), 60.0 Hz generator and measures an
rmscurrent of 0.570 A. What is the inductance?L =
mH
